Kotlin does not have the reputation of being the language of first choice for mathematical calculations, e.g. in the natural sciences or data science. Python, R and Julia share this market. Probably, the reason is that for many standard use cases there are no mature standard libraries available (yet) – which by the way is also true for Java – so Kotlin cannot benefit from that either.

With this website I would like to make a small contribution and and would like to introduce complex-numbers as first library.
